This study examined how caregiving experiences of spouses and adult children were different to each other in terms of caregiver characteristics, the impairment level of the elderly, caregiving time, caregiver burden, the effects of long-term care services, etc. Data were collected from 321 spouses and 324 adult children who cared for the functionally and/or cognitively impaired elderly using long-term care services. The main results are as follows. (1) Caregiver characteristics differed significantly between spouses and adult children. (2) Adult children cared for the more severely impaired elderly in terms of IADL, cognitive impairment, and behavior problems while spouses spent more time helping in ADL activities. (3) Spouse caregivers experienced greater overall burden, worry and strain, and financial burden compared to adult child caregivers. (4) Long-term care services were effective in reducing caregiver burden and improving family relations. Additionally, relations between adult child caregivers and the elderly was more improved than relations between spouse caregivers and the elderly after using long-term care services. Based on these findings, the differential experiences between spouse caregivers and adult child caregivers were discussed.
